Managing fungicide resistance means balancing today's control with tomorrow's risk
In short: A review of strategies for managing fungicide resistance in crop pathogens found that protecting the long-term effectiveness of these products is a genuinely difficult balancing act. The authors describe trade-offs between controlling disease now and slowing the evolution of resistance in pathogen populations over time.
Established tactics like rotating modes of action are well tested, but questions such as optimal dose rates, mixtures and spray timing remain debated and are studied through modelling, trials and monitoring.
The review notes that even a well-designed strategy only works if farmers actually follow it, and that communication with growers is often overlooked.
Why it matters: Protecting crop fungicides for the future means accepting trade-offs today, and strategies only work if growers actually adopt them.
